The invention discloses a transmission gear shifting device and belongs to the field of electric vehicles. The shifting device comprises a push-pull mechanism, a rotating mechanism and a shifting mechanism, wherein the push-pull mechanism comprises a linear reciprocating motion mechanism and a connecting rod or a lever connected with the linear reciprocating motion mechanism; the rotating mechanism comprises a push-pull barrel and a shifting rotating barrel opposite to the push-pull barrel; fixing sleeves are arranged on the peripheries of the push-pull barrel and the shifting rotating barrel; and a motion decomposition mechanism is arranged on the inner circumference of the fixing sleeve, the motion decomposition mechanism transmits axial motion to the shifting fork and simultaneously performs circumferential rotation, the circumferential rotation changes the pause position of the axial motion, and the shifting rotating barrel pauses once at the starting point or the ending point of the axial motion every time the axial motion is performed, so that the shifting rotating barrel is shifted once between a low-speed gear and a high-speed gear. According to the transmission gear shifting device, the gear shifting mode can be simplified, the gear shifting speed is increased, the driving hidden danger in the vehicle driving process is reduced, and the vehicle driving safety is improved.

    一种变速器挡位切换装置,属于电动车领域。切换装置包括推拉机构、转动机构和拨动机构,所述推拉机构包括直线往返运动机构和与其连接的连杆或杠杆,转动机构包括推拉桶以及与其相对设置的拨动转桶,推拉桶和拨动转桶外周设置有固定套筒,固定套筒内周设置有运动分解机构,运动分解机构将轴向运动传递到拨叉上同时做周向转动,周向转动改变轴向运动的停顿位置,每轴向运动一次,拨动转桶在轴向运动的始点或终点停顿一次,从而在低速挡位与高速挡位之间切换一次。本发明可以简化挡位切换方式,提高换挡速度,降低车辆行驶中的行驶隐患,提高车辆行驶的安全性。
